Fluorescent profiles of transgenic nematodes expressing NHX-5::GFP translational fusion protein. A genomic fragment containing the promoter and entire open reading frame of
nhx-5 gene was fused in-frame to GFP. The subcellular location of the fusion protein was determined by either conventional or confocal fluorescent microscopy. Fluorescent images are shown next to the corresponding differential interference contrast photomicrographs. O and P, NHX-5 is a pan-neural Na+-H+ exchanger that resides intracellularly, as shown in this fluorescent micrograph of the lumbar ganglion from NHX-5::GFP transgenic worms.
